KNOCKDOWN 80X.

SPECIFICATION forming part of Letters Patent No. 363,143, dated May 17,1887.

App ication tiled November 19, 1886. Serial No. 219,360.

To aZZ whom it may concern:

Beitknown that I, HENRY P. HUSTON, a cit-izen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have'invented certain new and useful Improvements inKnockdown Boxes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain new and useful improvements inreceptacles formed from material that may be readily bent or folded, andadapted tobe disjointed, so as to occupy a relatively smaller spaceduring transport or in storage to that which they inclose when puttogether in readiness for use Receptacles of this general character areknown to the trade as knockdown boxes. My invention contemplatesparticularly an improved conformation for such boxes and the blanks fromwhich they are formed, embodying simplicity and durability ofconstruction, economy of time, labor, and material in the process ofmanufacture, and ready manipulation in setting up and disjointing theparts.

I have illustrated my improvements in the drawings accompanying thisspecification, wherein- V Figure 1 represents in plan the configurationof the blank from which the body of the box or its cover is formed. Fig.2 represents a central section through the box-body and cover. Fig. 3represents in plan the box-bod y or its cover, and Fig. 4 represents thesame in perspective.

ployed in such manner as to leave a central rectangular portion, sideflaps, B B, pro

tongues from the end flaps, O O, render the tongues flexible, so thatthey may be readily manipulated in making and uncoupling the joint, ashereinafter explained. The auxiliary flaps b b I) b have projections e ec 6*, also flexible.

ln forming the body of the box or its cover, as the case may be-from oneof these blanks, I proceed as follows: The auxiliary flaps b b b I) arebent inwardly, (upon the lines 9 g and h h,) respectively, and securedat their upper edges to the interior surfaces of the side flaps, B B, bymeans of eyelets, as f f. f f or other wise. The side flaps are thenbent upwardly (along the lines m m and a n) at right angles to the mainportion of the blank. The tongues c c c c are thereupon bent upwardly(along the lines at m and n a) at right angles to the end flaps, O G.The end flaps are bent inwardly (along the lines 9 g and hi!) andbetween the side fiaps, B B, until the tongues c c, &c., pass theprojections e 6, data, as indicated in dotted lines in Fig. 2. The endflaps are then bent in a reverse direction until they are at rightangles to the main portion of the blank, and in this reverse movementthe tongues c c, 850., enter the space between the side flaps, B B, andthe auxiliary flaps ,b b, &c., passing behind the projections c e, 820.,thereby forming the complete receptacle or its cover, as indicated inFigs. 3 and a.

In knocking down or disjointing the box it is merely necessary to pushor bend the end flaps inwardly until the tongues c c'are disengaged, andthen bend the side and end flaps outwardlyuntil they lie in the samegeneral plane with each other. In this flattened-out condition thesmallest possible space for transportation or storage is occupied.

-It will be noted especially that the joints connecting the side and endflaps are wholly within the interior space when the parts are united.The receptacle therefore presents an even and neat exterior, and thejoint-pieces are protected from injury.

It is obvious that the form of the tongues c c, 8150., and the auxiliaryflaps b 1), 8m, may be varied within considerable limits withoutdeparting from thespirit of my invention, according to the degree offlexibility of the material employed and the dimensions or shape of thereceptacle to be produced.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, 1s-

1. A knockdown box havinga corner-joint consisting of a flap connectedto the interior surface of one of the sides, and a tongue conneeted withthe adjacent side and passing between the flap and first side,substantially as described.

2. A knockdown or folding receptacle having side and end flaps, the sideflaps being provided with receiving-pockets, each consisting of a stripconnected at its upper side and in ward end to the inner surface of theside flap, and the end flaps being provided with tongues engaging withinsaid pockets, substantially as shown and described.

I 8. A knockdown or folding receptacle having side and end flaps, theside flaps being provided with receiving-pockets, each consisting of astrip connected at its upper side and inward end to the inner surface ofthe side flap, and having a tongue projection, and the end flaps beingprovided with tongues engaging within said pockets, substantially asshown and described.

4. A blank of flexible material, for the purpose described, consistingof a rectangular central portion and rectangularwings B B C 0', havingthe extensions 1) b, 820., and the tongues c c, &e., substantially asshown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

HENRY P. HUSTON.
